链条传动是轴间机械传动的三种主要方式之一。由于链条传动平稳,挠性好,传递力大,安装精度要求不太高,因而已广泛应用于各种机械设备的传动和自动化生产线中成为一种主要基础通用件。现将国内外链条生产工艺进行对比以寻找差距,促进国产链条的发展。 Chain transmission is one of the three main ways of mechanical transmission between shafts. Due to the smooth transmission of the chain, good flexibility, large transmission force, and low installation accuracy, it has been widely used in the transmission and automatic production lines of various mechanical equipments as a basic basic universal part. Now we compare domestic and foreign chain production processes to find gaps and promote the development of domestic chains.
